SCREEN.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed August 3, 1906. Serial No. 329,059.

To all rwhom it may concern:

i Be it known that I, FRANCIS M. KEILER, a citizen of the United States, residing at Hanna City, in the County of Peoria, State of Illinois, have invented certain new and useful Improvements in Screens; and I do hereby declare the following to be a full, clear, and exactd-escription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to window screens` and has for its object, generally, to improve the construction shown in my prior patent No. 692,455, dated February 4, 1902, and in particular to adapt the main features shown in said patent to screens of the extensionA type, capable of adjustment to fit any ordinary sized window, thus embodying in a single screen the advantages heretofore, of necessity, separately limited to the above mentioned types.

Described in brief, the invention comprises a screen having top and bottom pieces, a pair of side sections, laterally movable along the inner face of said top and bottom pieces, and a screen proper having its upper end attached to said top piece, and its lower end to a roller disposed transversely of said side sections and movable thereon.

-With this end in view, the invention consists in the novel construction, combination, and arrangement of parts, all as hereinafter' fully described and illustrated in the accompanying drawings, in which:

Figure l is a front elevation of a window casing provided with an extension screen, constructed in accordance with this invention. Fig. 2 is a transverse section taken on the line 2-2 of Fig. l. Fig. 3 is a view in elevation of one of the side sections taken from the opposite side from that shown in Fig. l. Fig. 4 is an edge view of the same. Fig. 5 is a bottom plan view of a portion of the bottom piece of the frame, showing the beveled strip secured thereto.

Like parts are designated by corresponding numerals in the several views.

Referring more particularly to the drawings, the screen, which is shown in Fig. 1 in place in the casing 6 of a window, comprises top and bottom pieces 7 and 8, respectively, a movable screen 9 of any suitable material, such as Wire netting, attached at its upper end to the top piece, and at its lower end to a roller 10, and a pair of side sections l1, laterally movable along the inner face ofthe top and bottom pieces, the side edges of each section being formed by pairs of strips, between which the facing of netting of each section is secured. The outer member of each pair of strips extends partly across the top and bottom pieces of the screen frame at its respective ends, as shown. For clearness of description, the pair of strips l2 of each section adjacent the window casing 6, will be termed outer strips and those over which the roller passes will be termed inner strips and be designated by numeral 13.

The front members ofthe inner pairs of section strips 1S are provided with oppositely-disposed outward bevels 14, extending the entire length thereof, formed in a manner similar to the beveled strips shown in my original patent, and provided for a similar purpose. Each outer pair of strips 12 carries a metallic plate or insert 15, secured between the members thereof, and fitting in a correspondingly-shaped groove formed in each side of the window casing to hold the screen in place therein.

Roller' 10, to which the lower end ofthe screen proper 9 is attached, is provided with terminal drums 1G, upon which are wound cords I7, the lower ends of which are attached to eye-bolts mountedin the bottom piece 8, the drums being grooved for the better reception of said cords. The roller is transversely disposed with respect to the side sections, and extends beyond the beveled edges of each section a sufficient distance to admit ofthe lateral adjustment of said sections. Owing to the bcveled construction of said edges, it will be obvious that the side edges of the fabric forming the screen proper will be taken downwardly over the bevels to the face of said sections, thus forming a practically continuous screen, as shown in Fig. I and the cross section thereof.

By reason oi the cords being fixed, if the roller is moved upwardly, it will be rotated by the cords to wind up the screen, and if the roller be lowered, the screen will in like manner be unwound. To facilitate the manipulation of the roller, a knob 18 of porcelain, or other material, is secured to each end thereof exterior-ly of the drums.

The roller is retained in its upward or raised position with the screen wound thereon, by means of a keeper 19, secured to the top piece 7, the hook end of said keeper ttting around the adjacent roller drum. The bottom piece 8 carries an outwardly beveled strip 20, secured to its outer side face, as shown, directly below the movable screen, which latter fits closely against the face of said strip, when lowered, and is retained in such position by the tension of the cord upon the eyebolts and roller drums, and by its contact with the outwardly beveled face of strip 20.

The rear member of each outer pair of strips has secured to its ends metal straps 21, extending beyond the top and bottom edges of said strips-and across the respective frame pieces 7 and 8, such straps cooperating with the extended iront member of the section strips to formj troughs, in which said frame pieces fit, thus permitting the side sections to be moved laterally towards or awayfrom each other, along the inner face of the frame pieces, and, at the same time, preventing their accidental displacement from said frame pieces. The inward movement of the sections is limited by the beveled strip 20, the sides of which act as stops or shoulders, against which the inner edges of the side sections contact.

The screen can be obviously adjusted to fit Windows of any width, by means of the lateral adjustment of its side sections, with respect to the top and bottom pieces of the frame, and should the width of the window for which the screen is'desired be less than the length of the top and bottom pieces, it will only be necessary'to cut off a short section from the ends of said pieces, which are, in practice, formed of sutlicieut length for this purpose. The ends of the strips of the side sections may, in like manner, be sufliciently extended to admit of a similar operation.

Owing to the beveledY formation of the inner-'edges of the side sections and to the extension of the edges of the screen proper beyond each bevel, the several screen sections will fit so closely together as to result in the formation of a practically continuous screen.

Throughout the claims, the term fabric is employed with reference to the screen proper, and the term frame to the general outer structure of the screen.

It will be understood that, in practice, modifications of the specific construction shown, may be made, without departing from the spirit of the invention, which is, therefore, not intended to be limited to such exact construction.

What is claimed, is:-

l. A window screen comprising a frame having top and bottom pieces. a pair of side screen sections, and arolling screen disposed transversely of alld overlapping said side sections, said rolling screen comprising a fabric attached to said frame top piece and a roller to which the opposite end of said fabric is attached, said roller being adapted to run on said side sections, to roll or unroll said fabric, whereby the height of the opening between said side sections may be regulated.

2. A window screen comprising a frame having top and bottom pieces. a pair of side screen sections adapted to contact at opposite ends with the inner face of said top and bottom pieces,'a rolling screen disposed transversely of and overlapping said side sections and comprising a fabric attached to said top piece and a roller to which the opposite end of said fabric is fastened, said roller being adapted to run on said side sections, terminal drums carried by said roller and cords attached to said bottom piece and wound upon said drums to rotate the roller when it is raised or lowered, whereby the height of the opening between said side sections-may be regulated'.

3. An extension window screen comprising a frame having top and bottom pieces, a pair of side screen sections laterally movable along the inner face of said top and bottom pieces, and a rolling screen disposed transversely of and overlapping said side sections, said rolling screen coniprising a fabric'attached to said frame top piece, and a roller to which the opposite end of said fabric is attached, said roller being adapted to run on said side sections, to roll or unroll said fabric, whereby the height of the opening between said side sections may be regulated.
